need help with graphics32 library

I do not want to mess with installing the components

https://graphics32.github.io/Docs/_Body.htm

as I just need one transformation: rectangle to perspective quadrangle. So what I need is someone to tell me which procedure to use an which unit to declare in uses section. I will create Tbitmap32 dynamically. I shall also need help on detecting and convert 24 to 32 bitmap and vice versa .

You don't have to install anything but you could at least read the documentation and examine the examples...

Running examples requires installing components.

[Anders Melander 1784]

No it doesn't.

Looking at the source also doesn't require installing them

 

I'm a contributor to Graphics32 and I don't have the component installed.

I open

graphics32-master\Examples\Transformation\Transform\MainUnit.dfm

and see

object Src: TImage32

which means that component was put on the form, so had had to be installed as a component first.

[Anders Melander 1784]

You don't need to open the form to compile the project.

 

But if you need to see what the example source looks like, open the unit, ignore the error messages about unknown components, look through the source, close the unit without saving the changes.

I've already done it. There is not a single procedure to transform. There are several of them nested, probably four. The main one calls the next one and the fourth one (transform) is declared in another module. I don't have time to play with that puzzle. The modules have several thousand lines.

[Anders Melander 1784]

OK. Good luck then.

It's a shame you don't have enough time to do this.
